B. 11
C. 1
D. -9
Answer:
Blank 1 : 3
Blank 2: 3
Step-by-step explanation:
Let the unknown number for blank 1 be x.
The given problem is
Divide both sides by 4.
The answer for blank 1 is 3.
Let the unknown number for blank 2 be y.
The answer for blank 2 is 3.
The number in the blanks represents the same number.
If a number x is divided by another number m and gives the answer q without any reminder, then q is called the quotient.
Hence, the number here in blank represents the quotient.
A. (8x + 7)(2x-7)
O B. (4x + 7)(4x - 7)
O C. (8x-7)(2x-7)
O D. (4x-7)(4x-7)
Answer:
B
Step-by-step explanation:
16 x² - 49 ← is a difference of squares and factors in general as
a² - b² = (a + b)(a - b), thus
16x² - 49
= (4x)² - 7²
= (4x + 7)(4x - 7) → B
Answer:
B
Step-by-step explanation:
There is no number between 16x and 49. So only think about the number being squared for 49; which is 7.
Then 49 is negative, so you must have both positive and negative signs in both parenthesis. Otherwise, positive times positive is positive, and negative times negative is also positive.
4x4 is 16. That's why you put fours in front of Xs.
I am sorry for getting this wrong (if i did)
Well, OF is kind of the same with multiplication. So that question is indirectly saying 1%x$80. As you know, percent means over 100. So that will be;
1/100x$80
1/100 is 0.01. So that means 0.01x$80. And that is 0.8. So the answer is 0.8. Hope I helped.
